Cellulose is the most abundant naturally occurring macromolecule on earth, and cellulose nanocrystals (CNCs) are obtained by removing the amorphous regions in cellulose to retain the crystalline regions. The high aspect ratio and high specific surface area of CNCs give them excellent mechanical properties. Meanwhile, as a typical bio-derived nanorod with chirality, they exhibit strong birefringence phenomenon and produce colorful and unique structural colors, so they are commonly used in anti-counterfeiting responsive sensors and so on. Chitosan (CS) is the only alkaline cationic macromolecule containing free amino groups in nature. Chitosan fibers are commonly used in the medical field because of their unique properties such as good biocompatibility, degradability, and rapid hemostasis. However, due to the high surface charge density and high dispersion of CNCs, fibers are difficult to form by wet spinning, and the generally low strength of CS fibers limits their practical application in life. Therefore, the two can be synergized to promote the spinning and forming of CNCs in CS as an effective way to prepare functional fibers. Currently, some researchers have also used CNCs as reinforcement base to compound with bio-based functional materials in order to expand the application areas of CNCs, but little research has been done on the characteristics of CNC assembly in composite fibers that would result in structural coloration. On this basis, this paper innovatively prepares chitosan/cellulose nanocrystalline(CS/CNC) composite fibers by wet spinning method, and compares the mechanical properties and unique optical characteristics of the CS/CNC blended fibers and CS/CNC sheath-core composite fibers prepared by different blending and coaxial spinning methods. In this paper, the effects of different concentrations and temperatures on the tensile rheological properties of CS solutions were firstly investigated, and it was found that 2.5% CS solution was suitable for spinning at 60 ℃. Secondly, different concentrations of sisal CNCs were used to prepare CS/CNC sheath-core composite fibers to analyze the effect of CNCs concentration on the mechanical properties of the fibers, and the results showed that the mechanical properties of the fibers prepared with 2.0% concentration of CNCs were the most suitable. Therefore, 2.5% CS solution with 2.0% concentration of CNCs was selected for the preparation of subsequent wet spinning. To compare the structure and properties of composite fibers prepared by different spinning methods, the structure of CS/CNC composite fibers was analyzed by infrared spectroscopy. The comparison results showed that the FT-IR spectra of CS/CNC composite fibers were similar to those of CS fibers, with the main peak changes occurring in the characteristic absorption peaks between 3 650-3 200 cm-1. Due to the formation of new hydrogen and ionic bonds between CNC and CS, it is easy to form a network structure. Scanning electron microscopy was used to characterize the morphological structure of the fibers. The results showed that the cross-sectional CNCs of the CS/CNC blended fibers were assembled chaotically and twisted, whereas the diagonal cross-section of the CS/CNC sheath-core composite fibers had a distinct skin-core structure and the CNCs were assembled in the core layer into a lamellar structure. To further investigate the lamellar structure of the core layer assembled with CNCs, polarized light microscopy and circular dichroism spectroscopy tests were performed, and the CS/CNC sheath-core composite fibers showed two distinct positive peaks at 388 nm and 608 nm. It confirms that the core layer of CS/CNC sheath-core composite fibers has a left-handed helical nematic phase structure with uniform and orderly arrangement, and the fiber as a whole shows bright and orderly iridescent colors. The tensile mechanical properties of the fibers were tested, and the results showed that the mechanical properties of the CS/CNC sheath-core composite fibers were superior to those of the CS/CNC blended fibers, with an initial modulus of 489.40 cN/dtex, an elongation at break of 9.65%, and a breaking strength of 0.647 cN/dtex. The analysis by heat loss analysis and swelling property test showed that the thermal stability of CS/CNC composite fibers was more similar to that of CS fibers, and the network structure formed in the composite fibers could effectively impede the penetration of water molecules and improve the water resistance of CS/CNC composite fibers. The above results indicate that the CS/CNC sheath-core composite fibers prepared by the coaxial spinning method not only improve the mechanical properties of the fibers, but also have the unique optical characteristics, showing bright and orderly iridescent colors under polarized light. They are expected to be used for anti-counterfeiting clothing fabrics so as to further expand the application scope of CNC. [ABSTRACT FROM AUTHOR]

Hunan embroidery, as one of the four famous embroideries in China, is an embroidery technique with unique characteristics of Hunan and Hubei regions. However, with the technological upgrading brought about by the industrial revolution, mass production has become the mainstream manufacturing method of textiles, and traditional Hunan embroidery products have gradually declined in the mass consumption scene due to multiple factors such as complicated process, long construction period and high cost. Therefore, it is particularly important to inherit, innovate and spread culture of Hunan embroidery art products. In recent years, many scholars have carried out a series of studies on Hunan embroidery, mostly focusing on design element exploration, digital protection platform and other design practices, with a lack of attention to important production factors such as consumer demand and market development of Hunan embroidery products. Under the policy-oriented background of “cultural self-confidence” and “cultural power”, the cultural tourism consumption boom has swept across China, and the young groups in the new era who pursue individuality and attach importance to experience consumption have moved to the mainstream, promoting the mass market cultural tourism consumption demand gradually to the direction of individuation and diversification. In order to expand the market of Hunan embroidery cultural and creative products and promote the inheritance and dissemination of Hunan culture, this paper conducted research and analysis on young consumers（18-28 years old） of Hunan embroidery cultural and creative products, and used KANO model and Better-Worse analysis method to clarify the young consumers’ demand for Hunan embroidery cultural and creative products in the new era. Firstly, questionnaire distribution and in-depth interviews were conducted intensively in Yuelu Mountain and Orange Isle in Hunan province to obtain market research data. By integrating and analyzing the series demands of Hunan embroidery cultural and creative products, the expert team screened and classified the obtained demands of Hunan embroidery cultural and creative products by the hierarchical method, and divided the product demands into four levels: visual appearance layer, functional application layer, product quality layer and cultural connotation layer. Finally, the Better-Worse coefficient method was used to quantify the weight of each demand, and the sensitivity coefficient was increased to get the result. Based on the KANO model, it is found that among the 18 demands, undifferentiated demand（I） accounts for the largest proportion, that is, consumers of Xiang embroidery cultural and creative products are not sensitive to most of the demands of the products. According to the Better-Worse user satisfaction analysis method, the satisfaction order of various demands is calculated and it is found that the shape, color, after-sales service, interest, security and regional characteristics of Hunan embroidery products are ranked first. The results of the article suggest that doing a good job in the innovative design of Hunan embroidery cultural and creative products can start from the above needs to improve consumer satisfaction. Based on the KANO model and the analytic hierarchy process, this paper analyzes the consumer demand of Hunan embroidery cultural and creative products, which provides a theoretical method for the subsequent research on non-legacy cultural and creative products. Due to the complexity and volatility of the research samples in the selection of objects, the design of questionnaires and the implementation of interview research, it is difficult to avoid certain impact on the analysis results. Therefore, the research results may have certain limitations. In the future, factors such as humanity, region, gender and age will be further comprehensively considered, comprehensive analysis will be strengthened to provide comprehensive empirical reference, and the list of consumer demand for Hunan embroidery cultural and creative products will be enriched.

The textile image of “field hunting-patterned ribbon” unearthed from the tomb of Mashan Chu in the Warring States Period is the first to put the characters, animals and scenes in the same image. This paper improves the clothing and material system of the Warring States Period from a new visual angle. Through the research methods of imagology and narratology, the physical data and images of “field hunting-patterned ribbons” unearthed from the No.1 tomb of Chu in Mashan, Jiangling were analyzed step by step, and the image construction of field hunting characters was restored from the perspective of “pre-iconography description”, “iconography analysis” and “iconology interpretation”, the narrative characteristics of field hunting images were proposed, and the development reasons for the popularity of field hunting activities were excavated. First of all, the “pre-iconography description” focuses on the image construction of the “field hunting-patterned ribbon” fabric image, and restores the source of the “field hunting-patterned ribbon” image, the spatial composition form of “bottom line and horizon” and the role image. Secondly, the iconography analysis describes the narrative features of the fabric image of “field hunting-patterned ribbon”, and highlights the abstract visual effect, dynamic sportsmanship and juxtaposition of scene transformation through the narrative features. At last, by using the “iconology interpretation” to explain the reasons for the development of the “field hunting-patterned ribbon” fabric image, it shows that the field hunting activities led the life trend and social fashion at that time. The research shows that through the decomposition of iconography knowledge and deep digging of the image construction and restoration of “field hunting-patterned ribbons”, as well as the existence of image narrative intuitiveness, symbolism and synchronicity and other characteristics, one can feel the character endowed with a strong sportsmanship. These four image units are juxtaposed and synchronic because of their similar narrative characteristics of hunting culture. They set off the same theme and are placed in the same comprehensive space, showing Chu people’s unique artistic concept and aesthetic connotation. With the inevitable trend of multi-cultural thoughts and social unrest in the Warring States Period, a strange and novel hunting culture situation was opened up. This paper also summarizes that military, sacrificial, agricultural and entertainment factors were the main reasons for the popularity of hunting activities in the Warring States Period. In this paper, the uniqueness of “field hunting-patterned ribbons” lies first in its image. Based on the pattern image of field hunting-patterned ribbon fabrics in the Warring States Period, the color selection and pattern categories are summarized and the image construction is carried out. The essential purpose of the fabric is to deeply study the fabric itself, the social customs of Chu State in the Warring States Period, and the relationship between materiality and spirituality generated by artistic will based on the research method of image science and internal logic. At the same time, “field hunting-patterned ribbon” cleverly applied abstract visual effects and concrete scene modules in Chu art to clothing design in clothing fabric and culture, which is a continuation of its pursuit of freedom and unconstrained humanistic connotation and spiritual value.

China's digital economy exceeded 50 trillion yuan in 2022 accounting for 41. 5 percent of GDP. As the main focus of the development of the digital economy the digital transformation of enterprises is the in-depth integration of digital technology and production methods which contributes to reshaping an enterprise's business model and enhancing its innovation capability and has a positive impact on both enterprise value and enterprise performance. The textile and apparel industry as a traditional manufacturing industry in China is one of the important pillar industries of China's national economy. The digital economy can empower textile and apparel enterprises and gradually promote the digital transformation of enterprises which is of great significance to achieving the high-quality development of the textile and apparel industry and the sustainable development of enterprises. However at present the digital transformation of textile and apparel enterprises lacks theoretical and empirical guidance. The digital transformation path and the impact of digital transformation on enterprise value have not yet been clarified. Therefore based on the theoretical foundation of previous literature this paper takes textile and apparel enterprises as the research object and empirically studies the relationship between digital transformation and the enterprise value of textile and apparel enterprises. It aims to deeply analyze and explore the mechanism of the impact of the digital transformation of textile and apparel enterprises on enterprise value so as to provide ideas and suggestions for the digital transformation of textile and apparel enterprises and the improvement of enterprise value. Firstly this paper divided the digital transformation of textile and apparel enterprises into four dimensions based on TOE Technology-Organization-Environment theory including strategic leadership organizational empowerment technology driving and environmental support. By summarizing the previous literature the theoretical assumptions between the above dimensions and enterprise value were proposed. Secondly enterprise value was taken as an explanatory variable and Tobin's Q was selected to measure the level of enterprise value. The four dimensions of digital transformation of textile and apparel enterprises were taken as explanatory variables and the measurement indexes of the four dimensions were selected respectively. Moreover the entropy value method was used to assign weights to the measurement indicators to quantify the digital transformation of textile and apparel enterprises. Enterprise size asset-liability ratio and the ratio of cash to total assets were used as control variables. The theoretical model between the explained variables explanatory variables and control variables was constructed to test the impact of the digital transformation of textile and apparel enterprises on enterprise value. Thirdly the textile and apparel enterprises were screened from the A-share listed companies in Shanghai Exchanges and Shenzhen Exchanges and the annual data of the enterprises from 2017 to 2021 were selected as the initial sample. The initial samples were preprocessed and finally 61 textile and apparel enterprises were chosen containing annual panel data with a total of 305 observations from 2017 to 2021. The data were analyzed by standardization and descriptive statistics. According to the results of descriptive statistics it can be observed that part of the data has a wide range of polarity which indicates that there are obvious differences in the level of digital transformation of textile and apparel enterprises. In order to ensure the robustness of the subsequent analysis this article carried out logarithmic processing of the data. Finally Stata software was used to carry out the Hausman test on the model and the random effect model was used to carry out regression analysis and test the proposed theoretical assumptions. This study focuses on textile and apparel enterprises and divides the dimensions of digital transformation of textile and apparel enterprises enriches the research perspective of digital transformation of enterprises and empirically explores the impact of specific dimensions of digital transformation on enterprise value. The results of the study demonstrate that organizational empowerment technology driving and environmental support of textile and apparel companies have a significant positive impact on enterprise value. The effects on enterprise value in descending order are environmental support technology driving and organizational empowerment. Strategic leadership has no significant effect on enterprise value of textile and apparel enterprises. The above conclusions can provide theoretical guidance for the digital transformation of textile and apparel enterprises and provide targeted suggestions for accelerating the digital transformation of enterprises and increasing enterprise value. In future research the sample size can be further expanded. At the same time the digital transformation of textile and apparel enterprises in different regions of China can be compared and analyzed to understand the advantages and shortcomings of the development of textile and apparel enterprises in China. It is necessary to conduct a more profound and comprehensive discussion on the impact of digital transformation of textile and apparel enterprises on enterprise value by combining with questionnaire research and other methods.

In this paper, the effects of different orientations, size and temperature factors on the tensile deformation behavior of single-crystal body-centered cubic Fe nanowires were investigated using molecular dynamics simulations. The initial axial orientations of the iron nanowires are<001>, <110>,<111>,<102>, and <112>, and the deformation mechanisms were simulated at different temperatures (10-700K) and different size ranges (1.5 - 5nm). The results show that orientation, size and temperature significantly affect the tensile deformation behavior of single crystal body-centered cubic Fe nanowires. Molecular dynamics simulations show that <001> Fe nanowires with a diameter of 2 nm are deformed mainly through the mechanism of twinning under tensile loading at 300 K, and finally the tensile orientation is transformed to <110>. While at 700 K, the tensile deformation mode of <001 > Fe nanowires is dominated by slip mechanism. The deformation mechanisms of different initial orientations are very different at different temperatures and sizes, which leads to different mechanical properties of Fe nanowires. In this paper, we systematically investigate the transformation of the deformation mechanism of Fe nanowires under different orientations with the changes of size and temperature.

Colorectal cancer is a malignant tumor with high morbidity and mortality worldwide. Histone lactylation, a new protein post-translational modification, can be used as a potential biomarker for the diagnosis and treatment of colorectal cancer by regulating the structure of chromatin and gene transcription. This paper focuses on the role and mechanism of histone lactylation modification in the development of colorectal cancer. Additionally, the latest research progress and clinical experimental results are presented. This paper further shows that histone lactylation manipulates gene expression by affecting nuclear transcription factors and other epigenetic modifications involved in various life processes and subsequently regulates cell physiological function, revealing its regulatory mechanism and the functions of related enzymes. The relationships between histone lactylation and energy metabolic pathways such as glycolysis and oxidative phosphorylation are discussed in detail. The final part of this paper illustrates the important role of this modification in terms of the occurrence and development of colorectal cancer, cell metabolic reprogramming, and epigenetic regulation, supporting the clinical application of the use of histone lactylation as a biomarker.

This paper explores the political ecology of death and emotion through the secularized funeral rituals reform in Singapore. Although scholars have recently acknowledged the roles of emotion in shaping environmental politics, religion and death as socio-affective forces have not been substantively engaged with by political ecologists. In this paper, we argue that death is inherently both a spiritual and ecological phenomenon, as it addresses not only the spiritual landscape of how people see the natural world, but also the affective tensions and struggles over what counts as a "proper" form of burial in relation to religion and nature. We first investigate the way that the Singapore state utilizes ecological discourses to secularize Chinese death rituals, such that the death can be separated from the transcendent spheres and incorporated into the environmental biopolitics. Second, we examine how Chinese Singaporeans negotiate the emotional tensions in relation to the secularized rituals and especially the sea burials. This paper brings the issue of death into dialogue with political ecology and reflects on its emotional capacity in shaping environmental politics. [ABSTRACT FROM AUTHOR]

Specific path dependence occurs in the research of cross-border economic cooperation. Most of the existing studies are based on the current situation of collaboration and a certain period, while the studies on medium and long periods are relatively few. This paper took the process of international cooperation and development of the Tumen River sub-region as an example, constructed an analysis framework of the evolution mechanism of cross-border economic regional cooperation based on geography multi-scale thought, and discussed the essential characteristics and changing factors for international collaboration of Tumen River sub-region in each historical stage. The results show that: The international cooperation of the Tumen River sub-region has gone through four stages in the past 30 years: the development stage (1984-1992), the development boom period (1993-1996), the slowdown period (1997-2004) and the development restart period (2005-present). Besides, the cross-border economic cooperation in each stage of Tumen River sub-regional international cooperation begins based on the last round of material practice space, which has apparent historical inheritance and policy innovation in different stages. The impact is on cross-border regional infrastructure construction and urbanization development. The role of the United Nations Development Programme (UNDP) in sub-regional development is weakening, the leading role at the national level beefs up, the participation of provinces and local governments is increasing, and their integration with the regional development strategy is becoming increasingly close in the whole process under the general trend that political consultation and economic cooperation have become the global geopolitical environment changes. This paper helps in solvig the dilemma of international cooperation in the Tumen River subregion and enriching the theoretical research on cross-border cooperation of human geography.

Uric acid (UA), the final product of human purine metabolism, can cause hyperuricemia (HUA) when excessively accumulated. HUA is closely linked to chronic kidney diseases (CKD) and is considered an independent risk factor. Hyperuricemic nephropathy, a form of CKD induced by HUA, has seen significant advances in understanding through research into the pathogenic roles of uric acid and the development of HUA animal models. Although progress has been made in understanding the pathophysiological mechanisms by which UA induces CKD, much remains to be learned about its pathological molecular mechanisms. New approaches in animal modeling or the selection of model animals may potentially lead to significant breakthroughs in research on hyperuricemia as well as related CKD. This paper reviews the research progress on the molecular mechanisms of hyperuricemic nephropathy, focusing on oxidative stress, inflammation, autophagy, fibrosis, and gut microbiota. Oxidative stress is induced by uric acid intracellularly through xanthine oxidase, NADPH oxidases, and mitochondria, leading to cellular damage. In terms of inflammation, uric acid crystals can activate the NLRP3 inflammasome, triggering an inflammatory cascade. The role of free uric acid as a pro-inflammatory agent, however, remains controversial. Depending on the study conducted, autophagy has been found to either alleviate or exacerbate inflammation induced by uric acid. Fibrosis, particularly through epithelialmesenchymal transition (EMT), is a major mechanism by which uric acid causes glomerulosclerosis and tubulointerstitial fibrosis. Extensive research has explored various signaling pathways involved in uric acidinduced EMT. Beneficial gut microbiota protect the kidneys by synthesizing short-chain fatty acids, reducing urea’s enterohepatic circulation, and decreasing uric acid production. This paper aims to enhance understanding of the complex relationships between HUA and CKD, serving as a reference for further research and new drug development. [ABSTRACT FROM AUTHOR]

The 2023 China Health Report on Spine Degeneration noted a significant increase in lumbar surgery among patients under 35 years old in recent years, indicating a trend towards younger onset of cervical and lumbar diseases. Lumbar intervertebral disc herniation has become a major concern, making the study of disc degeneration pathogenesis and treatment methods clinically significant. At present, human intervertebral disc diseases are primarily diagnosed through imaging due to the challenges of obtaining tissue samples from the spine. Therefore, experimental animals have emerged as alternative research subjects because they are cost-effective, have short experimental cycles, and are easily accessible. Given the structural and physiological differences between human and other animal intervertebral discs, comparing their anatomy and histological characteristics forms the foundation of research into human disc degeneration. The purpose of this paper is to collect and review relevant studies on anatomical and histological structures of intervertebral discs in different animals and conduct a comparative analysis from four aspects, namely, intervertebral disc height, lumbar disc geometry, lumbar disc cartilaginous endplate characteristics, and extracellular matrix components. The results show that humans, kangaroos, sheep, pigs, and rats exhibit similar relative heights between the sixth and seventh cervical vertebrae. Mice possess lumbar disc geometries most akin to humans. Compared to other animals, humans have the thickest cartilaginous endplates and the lowest cell densities. The collagen within the fibrous annulus differs most notably in pigs compared to humans, while water content in the nucleus pulposus is consistent across pigs, sheep, rabbits, rats, and humans. Additionally, this paper describes the commonalities and discrepancies in disc degeneration manifestations between humans and animals, and summarizes modeling methods for disc degeneration in different experimental animals. Ultimately, the aims of this paper is to provide fundamental data for selecting suitable experimental animal models for the study of intervertebral disc degeneration. [ABSTRACT FROM AUTHOR]

[Objective] This paper reveals the spatiotemporal changes of vegetation in different ecosystems in Shaanxi Province, clarifies the influence mechanisms of different climatic factors and their interactions on the changes of vegetation, and provides a theoretical basis for regional ecological environmental protection. [Methods] Based on MODIS NDVI and annual average high temperature, annual average low temperature, annual average temperature, and annual total precipitation data, this paper analyzed the spatiotemporal variation characteristics of vegetation NDVI in each landscape partition from 2000 to 2020 by Theil-Sen Median trend, partial correlation, and geodetector, and the internal correlations and response mechanisms of vegetation NDVI changes with precipitation and temperature were investigated by combining variable separation. [Results] Vegetation NDVI in Shaanxi fluctuated and increased from 2000 to 2020 at a rate of 5.9%/per decade, among which the rate of vegetation NDVI decreased in the different landscape in the order: Northern Shaanxi＞Guanzhong＞Southern Shaanxi.The multi-year vegetation NDVI value of the province was 0.71, with high level in the south and low level in the north. Vegetation NDVI in 67% of the regions showed a significantly improved trend during the study period, and the proportion in different landscape decreased in the order: Northern Shaanxi＞Southern Shaanxi＞Guanzhong. The climate factors fluctuated over time in Shaanxi from 2000 to 2020, the change rates in different landscape decreased in the order: Shaanxi South＞Guanzhong ＞Shaanbei. The spatial trends of temperature factors showed the decrease in annual average high temperature, the increase in annual average low temperature, and the decrease in annual average temperature, and the increase in precipitation. The overall vegetation NDVI of Shaanxi and each sub-district from 2000 to 2020 was negatively correlated with annual average high temperature and positively correlated with annual average low temperature, annual average temperature, and annual total precipitation. The contribution of annual total precipitation was greatest in the province and northern Shaanxi, and the contribution of annual average high temperature was greatest in Guanzhong and southern Shaanxi. The interaction of annual average high temperature and total annual precipitation had the strongest influence on vegetation NDVI in the province, northern Shaanxi and southern Shaanxi, and the interaction between annual mean temperature and total annual precipitation had the strongest effect on vegetation NDVI in Guanzhong. The interaction of of precipitation with maximum and annual average temperatures significantly influenced the vegetation NDVI changes. [Conclusion] The vegetation in Shaanxi and the sub-regions had became better overall during the study period. The vegetation in each sub-region responded differently to climate, and the contribution of each factor and its interactions also differed. [ABSTRACT FROM AUTHOR]

Seedling emergence is a crucial stage in plant production as it greatly impacts or even determines the final yield. For dicotyledonous plants, the growth of the hypocotyl and the development of the apical hook play a significant role in seedling emergence. Hypocotyl growth and apical hook development are a continuously dynamic process and are important guarantees for seedling emergence. The elongation of the hypocotyls provides the necessary force for seedlings to penetrate the soil, while the apical hook protects the delicate apical meristems and cotyledons from the damages during the soil topping process. Focusing on the development of the hypocotyl and apical hook, this paper summarized the molecular mechanisms regulating hypocotyl elongation and thickening by arranging themselves through the cytoskeleton in dicotyledonous plants, as well as the growth mechanisms of cellular differentiation involved in apical hook formation, maintenance, and unfolding. This paper examined the synergistic effects and mechanisms of major environmental factors such as light and temperature, as well as plant endogenous hormones, on hypocotyl and apical hook development. Furthermore, the paper explored agricultural practices, including optimizing environmental factors through sowing methods and seedling thinning to enhance hypocotyl growth and apical hook development, which in turn improves seedling emergence rate and stand establishment rate. Lastly, the paper provided suggestions for further research on the molecular mechanisms regulating hypocotyl and apical hook development, along with insights into the adaptation mechanism of apical hook and hypocotyl development to adversity, as well as for achieving effective control of seedling emergence and stand establishment in dicotyledonous plants. This paper serves as a valuable reference for a deeper understanding of the seedling emergence mechanism in dicotyledonous plants and innovative plant seeding and seedling preservation techniques.

In order to obtain the new cellulose-degrading bacteria at normal temperature, a bacterial strain named as 18B with cellulosedegrading ability was isolated and purified from garden compost in this study. Congo red staining experiment and filter paper degradation experiment were conducted to verify its cellulose-degradation ability. 16S rRNA sequence alignment and whole genome alignment confirmed that it belonged to the genus Olivibacter, and was the closest to Olivibacter jilunii 14-2AT . Further comparative physiological and biochemical characterization revealed differences with O. jilunii 14-2AT in terms of growth temperature, oxidase and glycolysis. The strain 18B grew in the range of 12-48℃, and the optimal growth temperature was 30-37℃ . O. jilunii 14-2AT grew at 4-42℃ . Strain 18B was positive for oxidase and negative for glycolysis, while O. jilunii 14-2AT had no oxidase activity and was positive for glycolysis. Combined with the results of the genomewide covariance alignment, it was known that strain 18B had a certain evolutionary relationship with O. jilunii 14-2AT . The cellulose-degradation ability was found that the cellulase activity of 18B was up to 82.14+0.99 -9.90 U/L at 37℃, 200 r/min until the 5th d. Meanwhile, the enzyme activity could be maintained without degradation under the incubation conditions with sodium carboxymethyl cellulose as the only carbon source and only inorganic nitrogen source added. O. jilunii 14-2AT had no cellulose degrading ability and could not survive in a culture environment where sodium carboxymethylcellulose was the only organic carbon source. The results of whole genome sequencing showed that there were cellulase genes in the genome of strain 18B. The cellulase genes were heterologous expressed in Escherichia coli, and the degradation ability of the expressed products was tested. The results showed that the cellulase genes were active. The above results finally identified strain 18B as a new physiological strain of O. jilunii with cellulase activity. [ABSTRACT FROM AUTHOR]

his paper raises a query on the case report titled “A case of multivessel disease manifested by de Winter syndrome in ECG” published in this journal.

At the same time, we proposed it is not appropriate to describe de Winter ST-T changes in ECG as “syndrome”. [ABSTRACT FROM AUTHOR]

⑴ Background——There are few literatures on total factor productivity of forestry enterprises and its influencing factors from micro level. The performance of ESG includes the performance of enterprises in three dimensions: environment, social responsibility and corporate governance. It is an important indicator for the international community to measure whether an economic entity can achieve sustainable development. The discussion on the influencing mechanism of ESG performance on total factor productivity of forestry enterprises is of great significance for promoting high-quality economic development. ⑵ Methods——Based on the data of A-share listed forestry enterprises from 2011 to 2020,specific enterprises include forest cultivation industry, wood processing industry, furniture manufacturing industry, paper and paper products industry and other enterprises. Multiple linear regression model was used to analyze the impact of ESG performance on total factor productivity of forestry enterprises. And then, step-test procedure and bootstrap method were used to test the mediating role of innovation capability and internal control between ESG performance and total factor productivity in forestry enterprises. All the research data of forestry enterprises comes from the Wind, CSMAR,Straightflush and DIB database. ⑶ Results——The mean value of ESG performance and total factor productivity of forestry enterprises are 6. 302 and 8. 894 respectively. The total factor productivity of forestry enterprises with good, average and poor ESG performance are 9. 075,8. 808 and 8. 320 respectively. The results of One-way ANOVA show significant differences between groups at the 1% level. It shows that forestry enterprises with good ESG performance have higher total factor productivity. The regression coefficient of ESG performance on total factor productivity of forestry enterprises is 0. 1470（P=0. 01）,indicating that ESG performance has a significant positive impact on total factor productivity of forestry enterprises. ESG performance includes three dimensions: environment, social responsibility and corporate governance: Forestry enterprises’ undertaking environmental responsibility improves the utilization efficiency of forest resources and promotes the coordinated development of ecology and economy. Undertaking social responsibility helps to accumulate more social capital and form a harmonious internal and external environment. A perfect governance mechanism reduces agency costs and improves employees’ value creation ability, thus promoting the improvement of their total factor productivity. The result of the mediating effect model shows that forestry enterprises with good ESG performance can improve resource allocation efficiency by improving enterprise innovation capability and improve the internal control mechanism and reduce ESG risk so as to promote the improvement of total factor productivity. ⑷ Conclusions and Discussions——Good ESG performance of forestry enterprises is a key factor to improve total factor productivity. First, the government should improve the rules and regulations related to ESG,guide forestry enterprises to undertake ESG responsibilities through policy incentives and punishment mechanisms, encourage third-party organizations to participate in the credit rating of forestry enterprises ESG,promote them to improve the quality of ESG information disclosure. Second, forestry enterprises should attach importance to the idea of ESG,integrate ESG performance into their corporate strategies, and fulfill ESG responsibilities actively. Third, forestry enterprises should make full use of the mediating role of innovation capability and internal control, pay attention to the investment of innovation resources and the construction of internal control systems.

OBJECTIVE: At present, there are various surgical repair strategies for the lateral stability of chronic ankle instability after the injury of the lateral collateral ligament of the ankle, but the specific repair strategy to maximize the recovery of lateral stability of the ankle still lacks of evidence-based medical evidence. Based on this, for the first time, this paper systematically evaluated the effects of four popular repair strategies to restore the lateral stability of chronic ankle instability using the network meta-analysis method. METHODS: Computer retrieval was conducted on CNKI, WanFang, VIP, PubMed, Embase, Web of Science and Cochrane Library. The retrieval time was from the establishment of each database to December 2022. The randomized controlled trials or clinical controlled trials on different repair strategies to recover chronic ankle instability after injury of the lateral ligament of the ankle were included. The literature was screened and extracted. The literature quality was evaluated and data were analyzed using RevMan 5.4, R4.2 and Stata 14.2 software. RESULTS: Twelve studies (including 10 randomized controlled trials and 2 cohort studies) were included. A total of 673 patients with chronic ankle instability were involved in 4 repair strategies. The observation indicators were: anterior talar translation distance and talar tilt angle of ankle joint stress X-ray film (hereinafter referred to as anterior talar translation distance and talar tilt angle). The results of network meta-analysis showed that: (1) In terms of anterior talar translation distance, the sequence of reticular meta-analysis results from inferior to superior was anatomical repair > anatomical repair + enhancement of inferior extensor retinaculum > internal brake anatomical reconstruction > autologous/allogeneic tendon anatomical reconstruction. (2) In terms of talar tilt angle, the sorting results of reticular meta-analysis from inferior to superior were as follows: anatomical repair > anatomical repair + inferior extensor retinaculum enhancement > internal brace anatomical reconstruction > autologous/allogeneic tendon anatomical reconstruction. CONCLUSION: Anatomical reconstruction strategy of autologous/allogeneic tendon is the first in improving anterior talar translation distance and talar tilt angle, suggesting that this strategy may have the best effect in restoring the stability of chronic joint instability after injury of the lateral ligament of ankle, but more large sample, multicenter, double-blind randomized controlled trials are still needed in the future to further confirm.

This paper analyzes the operating efficiency of various types of family farms in economically under-developed hilly areas, finds out the existing problems and puts forward suggestions to promote the healthy development of family farms. Taking 591 family farms in Bazhong City as an example, this paper uses the input-oriented BCC model to measure and decompose the operating efficiency of planting, breeding and planting-breeding family farms. The results show that the comprehensive technical efficiency and pure technical efficiency of family farms have great room for improvement; breeding family farms have the highest comprehensive technical efficiency of 0.659, planting the lowest; the pure technical efficiency of planting and planting-breeding family farms is low, 0.628 and 0.602 respectively. The scale efficiency gap among the three types of family farms is small, and the scale efficiency is high. Farmers should be guided to participate in technical training to improve technical efficiency, especially planting technical efficiency. [ABSTRACT FROM AUTHOR]

The development of adjacent homogeneous tourism resource sites not only has the effect of enhancing tourism attraction with regional commonality, but also has obvious regional tourism substitution effect. Therefore, different models are often adopted in tourism development and operation to achieve different tourist experience effects and obtain better revenue. Based on the field survey and data analysis of Xidi and Hongcun villages in Yixian County, which are located in the same Hui cultural region, this paper finds that the development and operation models of the two villages have their own advantages and disadvantages, and different development models have an important impact on the perception of tourists and villagers. Combined with the new trend of tourism development, this paper discusses the strategy of protective development of ancient villages in the new stage, hoping to provide demonstration and reference for similar ancient village tourism development.

Due to the influence of environment and other factors, there are often abnormal data in dam monitoring data and the detection of abnormal data plays an indispensable role in the normal operation of the dam. However, the accuracy of traditional anomaly detection algorithms for dam monitoring data often fails to meet the requirements. In this paper, an anomaly detection algorithm based on Prophet GMM was proposed. The better fitting performance of Prophet algorithm was used to fit the dam data and the residual sequence was obtained from the fitting data and the actual data. Then, the residual sequence was clustered by GMM algorithm to accurately identify the abnormal value. The test results show that the method proposed in this paper can accurately identify outliers for different types of dam monitoring data. Compared with the traditional detection algorithm, it has significantly improved the detection indicators of precision, recall and accuracy. [ABSTRACT FROM AUTHOR]

Social security and high-quality economic development are important ways to achieve common prosperity. At the present stage, Chinese economic development has shifted from high-speed development to high-quality development. However, social security sustainability has been challenged by demographic transformation, which has an impact on the sustainability of economic development. It is also bound to further affect the coordinated relationship between social security and high-quality economic development. This article constructs an analytical framework for social security and economic high-quality development based on system theory. On the basis of elaborating the theoretical relationship between social security and high-quality economic development, the quality of social security and the index of high-quality economic development are comprehensively measured based on Chinese provincial panel data. The dynamic relationship between social security and economic high-quality development is also analyzed by using the decoupling theory and the coupling coordination degree. It is found that: first, both the quality of social security and the index of high-quality economic development show an increasing trend year by year. The indexes of social security quality and economic high-quality development are higher in provinces with faster economic development. However, in terms of the index growth rate, the economic quality development index of most economically backward regions grows faster than that of the economically faster developing regions. In contrast, the growth rate of their social security quality is slower than that of regions with faster economic development. This finding reflects that the quality of social security and the quality of economic development are not synchronized within regions. Second, the relationship between social security and high-quality economic development as a whole is characterized by decoupling, negative decoupling and fluctuating linkages, with the dominant decoupling showing a “progressive deterioration”. The high-quality economic development of each province mainly shows the trend of inefficient expansion. Third, the degree of coupling and the degree of coupling coordination of the two systems have both been on the rise year by year. However, they are still in a low state of coordination. Fourth, in the heterogeneity analysis, the system coupling and coordination degree of social security and economic high-quality development shifted from barely coordinated to primary coordinated in the eastern region. The central region evolves from on the verge of dysfunction to barely coordinated. In the western region, the degree of coordination of the system coupling between social security and high-quality economic development has evolved from mild to imminent coordination. All in all, the government needs to reasonably grasp the “appropriateness” of social security. And on the basis of making a bigger cake, it should share the cake well, so as to ensure that social security and the economy can achieve high-quality development on the basis of coordination and sustainability. Compared with the previous literature, this paper expands in the following two aspects: first, in terms of the selection of indicators, it is different from the existing studies that measure the level of social security only from the level of expenditure. This paper measures the quality of social security from the expenditure, income, coverage to collection of social security items. Not only the “quantity” but also the “quality” of social security is taken into account. Secondly, the mechanism of coordinated development between social security and high-quality economic development is analyzed on the basis of Luhmann's social system theory. It expands the relevant literature from a new perspective, and further measures the degree of coordination between the two. Through the results of the measurement, it finds the problems existing in the relationship between social security and economic development at the present stage in China, which will help the relevant departments to put forward reform measures.

In the digital age, Internet use has become important for relative poverty governance and common prosperity in China. “Internet + targeted poverty alleviation” is an essential boost to poverty alleviation that has experienced empirical tests. Academics have also paid attention to the poverty reduction effect of Internet use. On the one hand, existing studies mainly focus on its effect in rural areas, while relative poverty exists widely between urban and rural areas. Therefore, further comparison of the urban-rural differences in their poverty reduction effect is necessary. On the other hand, promoting capital accumulation is the fundamental mechanism of the poverty reduction effect of Internet use, which academics have poorly analyzed. Using the Chinese General Social Survey(CGSS)data in 2017, this paper uses the moderating effect, mediating effect, moderated mediating effect, and threshold effect models to examine the poverty reduction effect of Internet use and the urban-rural difference in its capital accumulation mechanism. The results find that Internet use can alleviate the relative poverty of individuals and has a more significant effect on rural residents than urban residents. Moreover, the results remain robust after overcoming the endogeneity problem using the instrumental variables model. Further mechanism analysis reveals that Internet use can transform online resources into offline human, social, and economic capital, thus alleviating relative poverty. Among them, the poverty reduction effect of human capital accumulated by Internet use is stronger for urban residents, and the poverty reduction effect of economic capital is more substantial for rural residents. Meanwhile, there are threshold conditions for human capital, economic capital, and social capital for the poverty reduction effect of Internet use. Furthermore, there are urban-rural differences in the threshold values. The contribution of this paper to the existing research lies in the following aspects: first, it places urban and rural residents in the same framework and uses different poverty measurement criteria to compare the differences in poverty reduction effects generated by Internet use. Second, to break the dichotomy method used in previous poverty studies, this paper pays more attention to the relative characteristics of relative poverty, takes the difference degree between individual living standard and average level as the index of relative poverty measurement, and generates the variable of relative poverty depth, which is an innovation of poverty measurement. Third, it reveals that the accumulation effect of capital(economic, social, and human capital)generated by Internet use is the fundamental poverty reduction mechanism and further analyzes its urban-rural heterogeneity and threshold conditions. The results suggest that, on the whole, Internet use has a more significant poverty reducing effect on rural residents than on urban residents. Thus vigorous development of Internet infrastructure in rural areas remains an important initiative for future relative poverty governance. The accumulation of human capital is the fundamental mechanism of Internet poverty reduction, warning us to pay attention to enhancing human capital. The top priorities for future poverty governance are relatively poor residents in urban areas and relatively poor “marginal” populations in rural areas. [ABSTRACT FROM AUTHOR]

Realizing the common prosperity of farmers and rural areas is the most difficult and heavy task in China, which means that strengthening and innovating rural governance will undertake more goals and tasks to achieve common prosperity. Therefore, it is necessary to build a community of rural governance from the perspective of common prosperity to achieve a high degree of unity between common prosperity and effective governance in rural areas. However, the existing research has rarely taken common prosperity as the breakthrough point and carried out the research on rural governance community from this perspective, especially the research attention on how common prosperity guides and promotes the construction of rural governance community and how the construction of rural governance community can effectively promote common prosperity is not enough. Firstly, this paper analyzes the internal relationship between the realization of common prosperity and the construction of rural governance community, and finds that realizing common prosperity is the basic premise and value orientation in the construction of rural governance community, while the construction of rural governance community is the realization and essential requirement of common prosperity, which shows the internal coupling relationship between the two ways and purposes of mutual realization. Secondly, based on this internal relationship, we can find that the foundation of the internal unity of the Marx's community thought and urban-rural relationship theory is its theoretical origin, the realistic guidance of the internal unity of Xi Jinping's Thought on socialism with Chinese characteristics for a new era's common prosperity thought and rural governance thought is its theoretical innovation, and the contemporary sublimation of “Great Harmony” and rural governance thought in Chinese excellent culture is its theoretical foundation. Finally, on its implementation path, we need to strengthen Party building and strengthen the “connotation” and “extension” of coordinating the rural governance community, to develop rural collective economy to build the material foundation of rural governance community, and to improve the rural governance system of “Three Governance Integration” and the governance mechanism of rural governance community. Besides, we need to actively promote urban-rural integration and activate the endogenous motivation of rural governance community. Compared with the previous literature, this paper expands in the following two aspects:first, it combs the internal relationship between the realization of common prosperity and the construction of rural governance community, and clarifies the theoretical premise of in-depth discussion of rural governance community and its construction from a new perspective of common prosperity. Secondly, in the analysis of theoretical logic, it pays attention to the basic principles of Marxism and its combination with China's reality and Chinese excellent traditional culture. Instead of thinking about the governance community in the rural category, it innovatively discusses the rural governance community and its construction from the overall situation of urban-rural integration based on economic relations and the basic trend of rural governance modernization. The research in this paper may enrich and expand the theoretical horizon of the study of rural governance community to a certain extent, reveal the internal relationship between common prosperity and rural governance community, help relevant departments in China to provide ideas and references for policy making in rural governance practice at present, promote rural governance effectively and solidly promote farmers' common prosperity in rural areas.

To build a new development pattern with the domestic cycle as the main body and the international and domestic dual cycles reinforcing each other, it is necessary to take the expansion of domestic demand as a strategic basis, and the expansion of household consumption is an important part of it. By realizing people-centered urbanization, the new urbanization construction has promoted the release of residents' consumption potential from both supply and demand aspects, and provided a driving force for China's economy to effectively expand domestic demand. However, there is a lack of empirical analysis of the relationship between new urbanization and residents' consumption potential at the macro level. Based on the panel data of 280 cities in China from 2007 to 2019, this paper empirically studies the impact of new urbanization construction on the release of residents' consumption potential on the basis of measuring the level of new urbanization construction and residents' consumption potential, and analyzes its mechanism from the supply and demand sides of the consumer market. The study finds that the new urbanization construction can realize the expansion and upgrading of the consumer market on the supply side, promote the increase of residents' income and the improvement of consumption security on the demand side, and then fully release the consumption potential of residents. This result still holds after a series of robust tests and treatment of endogeneity problems. Further analysis shows that the new urbanization construction has a stronger effect on the release of residents' consumption potential in the eastern and northeast regions, and at the same time, the degree of industrial agglomeration and the level of digital economy development also have a positive moderating effect on the release of urban residents' consumption potential. The results of nonlinear analysis show that the release effect of new urbanization on the consumption potential of urban residents is gradually amplified, and with the improvement of the level of new urbanization, its release effect on the consumption potential of residents also gradually increases. Compared with previous studies, the marginal contribution of this paper is mainly reflected in the following three aspects: firstly, from the perspective of research, the logical framework of new urbanization construction to release residents' consumption potential is constructed from the supply and demand sides of the consumer market, and the urbanization construction is linked to consumption growth, and how to rely on urbanization to release the strategic potential of residents' huge consumption. Secondly, in terms of measurement methods, the index system of new urbanization construction level is constructed from five aspects: population urbanization, economic urbanization, social urbanization, resource spatial intensification, and urban-rural integration, besides, the level of new urbanization construction is measured, and the consumption potential index system of residents, consumption willingness and consumption environment is designed from the three dimensions of consumption capacity, then the consumption potential of residents is measured, This method is more direct and specific than that of DID, which uses a simple 0-1 variables. Thirdly, in terms of data use, a number of medium and micro databases such as the city panel database, the industrial enterprise database, and the macroeconomic and real estate database of the State Information Center are used, and the data is more abundant and reasonable. This paper reveals the key role of urban development and industrial support in unleashing the consumption potential of residents, and puts forward policy suggestions such as diversifying consumption scenarios, supporting micro, small and medium-sized enterprises, improving the social security system, and optimizing the industrial structure, which is conducive to the further improvement of the new urbanization strategy in the future and provides a policy starting point for giving release to the potential of the domestic market.

Common prosperity is an important feature of Chinese path to modernization, and urbanization is a necessary path to achieving Chinese path to modernization. However, the current urbanization of counties is plagued by problems such as unbalanced regional development, widening gap between urban and rural areas, unsound infrastructure construction, and imperfect public service support, which constrains the realization of common prosperity. How to build a scientific and reasonable evaluation system to assess the development level of county urbanization and the degree of urban-rural integration is of great significance in promoting the healthy development of county urbanization and realizing common prosperity. This paper systematically reviews the historical origin and theoretical connotation of common prosperity, explores the internal mechanism of county urbanization for common prosperity, and then bases on Amartya Sen's proposition that social development should be a continuous expansion of the “feasible range of capabilities” of human beings in order to realize greater substantive freedom, arguing that realizing the “common prosperity” as well as the “realization of free and comprehensive development of human beings” implies a continuous expansion of the scope of the feasible range of people's capabilities, and that, from the concrete point of view, not only the incomes of the inhabitants should be made fair and reasonable, but also the range of commodities and services that can be consumed by the urban and rural inhabitants should be continuously expanded, and the gaps between the groups should be continuously narrowed. Therefore, based on the principles of systematicity, scientificity, objectivity and foresight, this study is based on the data from the Statistical Yearbook and the big data from the platform of “ Data Intelligence Portal for Social Science Studies”(DIPS)developed by the “Joint Laboratory of Data Intelligence and Urban Future of Zhejiang University-Zhejiang Mobile”. The evaluation system of county urbanization is constructed from the three evaluation dimensions of income fairness, consumption fairness and urban-rural integration(first-level indicators), which includes 9 second-level indicators including indicators like affluence level, development potential and urban-rural income disparity etc. and 26 third-level indicators. Compared with the previous literature, this paper expands in the following two aspects: firstly, this study establishes a theoretical connection between common prosperity and county urbanization, and tries to construct a county urbanization evaluation system from this new perspective. The three-dimensional division of income fairness, consumption fairness and urban-rural integration structurally realizes the organic convergence of the value goal of common prosperity and the policy goal of county urbanization, takes into account the specific requirements of common prosperity on the income side and the consumption side, and also highlights the precision policy of county urbanization on urban-rural integration, which meets the requirements of the top-level design of the evaluation system of high-quality county urbanization based on the goal of common prosperity. Secondly, unlike the existing evaluation system that relies on statistical yearbook data, this research adds big data indicators that are accessible, identifiable, analyzable and replicable to the selection of indicators, so that the indicators not covered by the traditional statistical yearbook data can be meticulously portrayed in real-time feedback, helping to accurately capture the dynamic characteristics of the current urban development, and ultimately combining the advantages of the two to make the evaluation system of county urbanization more scientific and innovative. This study reveals, to a certain extent, the theoretical connotation between the national strategic goal of common prosperity and high-quality urbanization in counties, and the constructed indicator evaluation system not only provides academic references for decision-making and practice of urbanization construction, but also guides local governments to achieve the optimal allocation of resource elements between urban and rural areas and the bidirectional and efficient flow of resources, so as to promote the coordinated advancement of the common prosperity and the integration of urban and rural areas with high-quality development.

Urbanization construction has always been one of the key development directions in China, and the process of urbanization faces many risks and challenges. In the context of complex and diverse urban risks, major public health risks are one of the most significant ones in terms of impact and destructive power. The outbreak of the COVID-19 at the beginning of 2020 has evolved from a public health event to a global economic and social crisis, reflecting that China has room for further improvement in the prevention and control system of major public health risks, and the modernization of urban governance has a long way to go. It is urgent to explore the establishment of a comprehensive prevention and control system for major public health risks in cities that is in line with the process of urban development in China. The general theoretical research on risk governance in the academic community is relatively rich. The research on the public health risk prevention and control system was mainly concentrated before 2010. After the outbreak of COVID-19, China's research on major public health risk governance was once again valued by the academic community. However, the existing research is generally decentralized and fragmentation, without forming systematic theories and views. Compared to previous studies, this article focuses on the development and evolution of major public health risks, integrates the concept of “full cycle management” and dynamic prevention and control, and takes the formation of comprehensive and full cycle closed-loop management as a breakthrough and innovation. It sorts out the theoretical framework of urban major public health risk assessment and decision-making mechanisms, breaks through the limitations of existing risk governance, and achieves full cycle coordination and full process integration, To ensure the lives, health, and social stability of the people, and provide directional inspiration for further improving the governance level of major public health risks in China. Based on the background of “risk society” and the principle of risk early warning, this paper follows the process of risk occurrence and puts forward the connotation of major urban public health risks in this paper on the basis of defining relevant concepts. Guided by the concept of “full cycle management”, combined with the 4R crisis management theory, risk management theory, and holistic governance theory, the dynamic core awareness throughout the entire risk prevention and control process is integrated to construct a theoretical framework for the dynamic prevention and control of major public health risks throughout the entire process. Based on the actual situation of social gatherings, the structural and functional characteristics that should be possessed in the dynamic prevention and control of major public health event risks throughout the entire process are determined. From the perspectives of “ considering system as the core” and “risk as the main line”, this paper makes a unified top-level design plan, exploring the practical path of constructing a risk assessment system that includes risk identification, risk assessment, risk assessment, and decision support, as well as a risk control mechanism that includes emergency response and normalized control, and designs a major urban public health risk control mechanism, which transforms from traditional consequence emergency response to early risk regulation prevention and control capabilities, and thus forming a major public health risk prevention and control system of “comprehensive risk assessment, early warning, precise dynamic response control” throughout the entire process. In this paper, risk control is divided into two processes: emergency response and normalized control, that is, to design an emergency response mechanism of multi-department coordination and a normalized control mechanism of major urban public health risks, so as to solve the dilemma of emergency fragmentation and form a full-cycle closed-loop management.

Expensive medical treatment(“Kan Bing Gui” in Chinese)refers to the high cost of converting medical and health resources into medical and health services, and the quantity and quality of medical and health service supply under limited resources are difficult to meet public health needs, thus directly affecting the construction of Healthy China Initiative. Moreover, the explosive growth in healthcare demand brought by the rapid aging of China's population will create additional pressure on the healthcare system and exacerbate the mismatch between supply and demand. Consequently, solving the “Kan Bing Gui” problem is a crucial task to ensure the achievement of the goals of the Healthy China Initiative. Many related studies simply attribute the “Kan Bing Gui” problem to insufficient fiscal expenditure on health, which is inconsistent with the fact and lacks in-depth analysis of the underlying institutional mechanisms behind the problem. Based on the perspective of structural imbalance in the allocation of medical and health resources, this paper studies the relationship between “Kan Bing Gui” problem and fiscal expenditure on health. Firstly, by summarizing the characteristic facts, we condense two main theoretical hypotheses:(1)The imbalanced allocation of medical and health resources is a major contributor to the “Kan Bing Gui” problem;(2)An increase in fiscal expenditure on health will aggravate the structural imbalance in the allocation of medical and health resources and hinder the alleviation of the “Kan Bing Gui” problem. Secondly, we empirically confirm the above two hypotheses with provincial panel data from 2009 to 2019, using Feasible Generalized Least Squares(FGLS)and mediation testing. Finally, we conclude that increasing fiscal expenditure on health will ultimately worsen the structural imbalance in the allocation of human resources, which is not conducive to solving the “Kan Bing Gui” problem. For the sake of truly alleviating the “Kan Bing Gui” problem from the whole society, increasing fiscal expenditure on health should be combined with in-depth reforms of the health care system to fundamentally optimize the allocation of medical and health resources, and then improve allocative efficiency. Compared to existing literature, this paper has three contributions. Firstly, we analyze the “Kan Bing Gui” problem at social level rather than just at an individual or family level. Although the long-term high total cost of social health is difficult to be perceived by the public and has strong concealment, it directly affects the implementation of the Healthy China Initiative. Secondly, this paper is based on the imbalanced allocation of medical and health resources, and mainly concentrates on the structural imbalance in the referral system. We explore the institutional factors of the “Kan Bing Gui” problem by analyzing the underlying causes of the imbalanced allocation of medical and health resources. This paper can provide a theoretical basis for fundamentally solving the “Kan Bing Gui” problem and correctly understanding the government expenditure responsibility. Thirdly, this paper delves deeper into the coordination mechanisms between efficient market and effective government to achieve a rational allocation of medical and health resources. This paper proposes a new idea to solve the “Kan Bing Gui” problem by fully coordinating the tripartite mechanism of the government, market and society, and combine the increasing of government health expenditure with the deepen reform of health care system. “Kan Bing Gui” has been a long-standing issue in China. In recent years, various kinds of studies have examined the causes of this problem, but this paper provides a unique perspective to explore the impact of structural imbalance in referral systems on this problem, as well as the systematic mechanisms behind the problem, and also puts forward useful ideas and references for the construction of the Healthy China Initiative.

In recent years, China's utilization of FDI, despite the challenges it has faced, has managed to “buck the trend” of the global decline in outward FDI, the underlying logic of which is that the “dual circulation” can create a new advantage in attracting FDI. However, there are few direct analyses in the existing literature on the link between the new development pattern of the dual circulation and the “stable improvement” in the quality of FDI. Among the many factors affecting FDI, even the studies conducted from the perspective of the dual-circulation mainly focus on qualitative discussions or certain specific factors in the domestic and international macro-circulation, failing to focus on the possible impact of the dual-circulation itself on China's “steady improvement of the quality of utilization of FDI”. This paper, by adopting the Asian Development Bank(ADB), the University of International Business and Economics Global Value Chain Database(UIBE GVC), and the China Carbon Accounting Databases(CCADs), etc., based on Ni Hongfu et al.(2016)'s method of measuring the length of domestic and international production segmentation, quantitatively measures the “double cycle” and examines the effect of “ dual circulation ” on the “quality” and “quantity” of foreign investment utilization. The empirical study finds that the domestic and international dual circulation and their interaction play a significant role in promoting the “quality” and “quantity” of FDI utilization. Specifically: the improvement of industrial supporting capacity and demand expansion under the scale advantage of the local market, as well as the increase in the degree of openness, are the key mechanisms for the dual circulation to promote the utilization of FDI “steadily improving quality”; “The quality of the system plays a significant positive regulatory role in the promotion of “steady improvement in the quality” of foreign capital utilization, that is, the more perfect the quality of the system, the more conducive to the dual circulation promoting the utilization of foreign capital; the results of the heterogeneity test show that the dual circulation has a more significant effect on the promotion of the tertiary industry, and due to the existence of market segmentation between regions, the dual circulation has a more significant effect on the promotion of the tertiary industry than the central and western inland regions. At the same time, due to the existence of inter-regional market segmentation, the domestic and international dual circulation has a more significant effect on the “quality” and “quantity” of foreign capital utilization in the eastern coastal region than inland areas in the central and western regions. The possible marginal contributions of this paper include: in terms of research perspective, different from the factors influencing the utilization of FDI, including high-quality utilization of FDI, which has been the concern of the existing research literature, this paper focuses on expanding the analysis of the factors influencing the utilization of FDI to improve the quality in a stable manner from the perspective of the domestic and international dual circulation; In terms of research content, regarding the possible impact of the dual circulation on the utilization of foreign investment “steadily improving quality”, it not only analyses its possible real effects from the theoretical and empirical levels, but also tries to reveal the possible mechanism of the above impacts; in terms of measurement methods and data usage, on the one hand, based on the input-output table, this paper uses the consumption coefficient matrix, Leontief inverse matrix, value-added matrix, etc. to measure the length of the domestic and international production splits, which is an innovative way to quantitatively measure the dual-circulation; on the other hand, in contrast to the previous studies of the dual-circulation that stayed on the panel data at the national level, the object of this paper's research is further refined to the provincial and industry levels to carry out a more detailed study. The research in this paper not only helps to expand and deepen the understanding of the influencing factors of China's utilization of FDI, but also provides policy insights for government departments on how to continuously improve the supporting capacity of the industries that utilize FDI and cultivate new advantages in attracting and gathering FDI under the new situation from the specific perspective of the new development pattern of the dual circulation.

Currently, the level of localization and autonomy in advanced manufacturing in China is relatively lagging behind developed countries, and there are still many areas where “we are inferior to others in technology” and “we are still dependent on others”. Modern service industry and advanced manufacturing industry represent the direction of “modernization” and “progressiveness” of China's industrial development. “Two industries” convergence is an important point for China to participate in great power competition and industrial competition, and an important way to achieve high-quality development of advanced manufacturing industry. Based on this background, this paper classifies and summarizes the modern service industry and advanced manufacturing industry by using statistical relevant data from the two major industries. Firstly, to measure the degree of integration between advanced manufacturing and modern service industries in different provinces and industries in China, this study builds an index system and a coupling coordination degree model, therefore, the measurement of coupling degree in different industries is more detailed and accurate. Secondly, using data from A-share listed companies in China from 2003 to 2021, this study empirically tests the impact of the integration of the two industries on the total factor productivity(TFP)of advanced manufacturing. This research has shown that the integration of the two industries has significantly improved the TFP of advanced manufacturing industry, and this result still holds true after a series of endogeneity treatments and robustness tests. Heterogeneity analysis shows that the integration of the two industries has more significant impact on the TFP of advanced manufacturing in state-owned enterprises and large enterprises. Besides, the integration of some specific industries like specialized equipment manufacturing, computer, communication, and other electronic equipment manufacturing with modern service industries can significantly improve industry TFP. The possible contributions of this article are as follows: firstly, this paper theoretically explains the logical relationship between the integration of “two industries” and TFP of advanced manufacturing industry and reveals the influence mechanism of “two industries” integration on TFP of advanced manufacturing industry mainly from three aspects: promoting technological innovation through technological integration, alleviating financing constraints through the integration of digital economy and real economy, and optimizing resource allocation through market integration. Secondly, this paper matches macro province-industry data with micro enterprise data, as the different dimensions of data measurement to some extent avoid endogeneity issues of reverse causality. This is because individual enterprise behavior usually cannot affect the degree of integration between provinces and industries. Thirdly,heterogeneity analysis was conducted on advanced manufacturing enterprises in different industries. Based on the above conclusions, this article finally proposes policy recommendations from the aspects of actively developing the digital economy and modern service industry, encouraging collaborative innovation among enterprises, and reducing barriers to factor mobility.

In recent years, a large number of new digital information technologies have appeared in the world. The role of the digital economy as a “stabilizer” and “accelerator” for the development of the real economy has become increasingly prominent. Digital transformation has become a key force in reshaping the global resource structure and changing the world economic pattern. Especially in the current era, the international political, economic and scientific and technological landscape is constantly changing. How to grasp the new situation, strengthen technology leadership, improve digital governance and establish new development advantages have become a severe test for each economic entity. However, the relationship between business uncertainty and digitization is still inconclusive. The unpredictability of the environment has led enterprises to rely more on digitization. Enterprises are eager to carry out comprehensive digital construction at the fastest speed to improve their competitive position. Companies are trying to be a dark horse in the face of environmental shocks. However, in practice, it is found that the situation, ecological environment, capital, technology and other constraints lead to the inability of enterprises in the digital construction. Therefore, the study of how the uncertainty of the business environment affects the digital transformation of enterprises has become the focus of this paper. Specifically, through the analysis of resource-based theory, agency theory, real option theory, strategic alignment theory and existing research results, the main hypothesis and alternative hypothesis of the paper are proposed. The empirical part uses the data of China's A-share listed companies from 2004 to 2021 to test the impact of business environment uncertainty on enterprises' digital transformation. The results show that uncertainty in the business environment will inhibit enterprises' digital transformation. However, this inhibitory effect will weaken as the uncertainty of the business environment increases. The influence of business environment uncertainty on digital input and results conforms to the U-shaped relationship, but it only inhibits the efficiency of digital output. Uncertainty in the business environment inhibits digital transformation through financing constraints, technical talent drain, and management myopia. Accordingly, this inhibition can be alleviated by promoting market-oriented development, promoting the construction of digital organizations and increasing the proportion of management ownership. The inhibiting effect of business environment uncertainty on enterprises' digital transformation is more significant in enterprises with overseas management background, non-IT management background and higher average age of management. Moreover, this dampening effect ultimately leads to a decline in aggregate productivity and firm value. Compared with previous literatures, the conclusions enrich the research on the impact of business environment on enterprises' digital transformation. The internal logic and economic consequences of business environment uncertainty inhibiting enterprises' digital transformation are deeply discussed. The corresponding mitigation mechanism is studied according to different influence channels. The heterogeneity is analyzed based on the characteristics of management structure. The relationship between business environment uncertainty and enterprise digital transformation is analyzed comprehensively. At the same time, it provides new empirical evidence for the development of China's digital economy and the high-quality development of the market. [ABSTRACT FROM AUTHOR]

At present, the Ukraine crisis has triggered the accelerated evolution of the world geopolitical pattern. Trade frictions and the impact of the COVID-19 epidemic have increased the risk of rupture of the global industrial chain. In this context, countries have shifted from pursuing “efficiency” of the industrial chain to emphasizing both “efficiency and security”, and the issue of industrial chain resilience and security has been raised to unprecedented new heights. Improving the resilience of the industrial chain is a key component in promoting high-quality development and maintaining national security. Based on the multi-regional input-output table(ADB-MRIO)compiled by the Asian Development Bank, this paper calculates the resilience of the industry chain, then combines it with industrial robots data provided by the International Federation of Robotics(IFR)to deeply explore the impact and mechanism of artificial intelligence on the resilience of the industry chain. The study shows that:(1)overall, artificial intelligence can significantly improve the resilience of the industry chain. This result is still significantly valid under robustness tests such as dealing with endogenous problems, changing variables, changing sample range, and changing estimation methods.(2)The mechanism test results show that the effects of technological innovation and governance system optimization are the internal mechanisms for AI to enhance the resilience of the industrial chain.(3)The heterogeneity analysis shows that at the national level, artificial intelligence has a more significant impact on enhancing the resilience of industrial chain in developed countries and countries with higher levels of digital infrastructure penetration. At the industry level, compared to low tech manufacturing, artificial intelligence plays a more prominent role in enhancing the resilience of the industrial chain in mid to high tech manufacturing.(4)When considering the impact of the 2008 financial crisis, we also find that the financial crisis has weakened the positive effect of artificial intelligence on the resilience of the industrial chain. This paper contributes to the existing literature in three aspects. First, in terms of research issues, this paper provides a possible path to effectively improve the resilience of the industrial chain from the perspective of artificial intelligence, and further enriches the research on the determinants of industrial chain resilience. At the same time, we also put forward the internal mechanism of artificial intelligence to improve the resilience of the industrial chain, that is, artificial intelligence will affect the resilience of the industrial chain through two possible channels: technological innovation effect and governance system optimization effect. Second, in terms of index construction, based on the analysis of industrial chain resilience in the International Monetary Fund's World Economic Outlook Report, this paper uses the input-output method to construct the index of industrial chain resilience at the country-industry level from the perspective of intermediate input diversification, providing empirical evidence for accurately identifying the industrial chain resilience in various industries and countries. Third, in terms of research data, this paper manually links the multi-regional input-output table(ADB-MRIO)and the International Federation of Robotics(IFR)to form the dataset needed for this research. In addition, the sample interval of this study is from 2007 to 2019. Compared with previous studies using the WIOD input-output table up to 2014, it can better reflect the current new pattern of global economic and trade adjustment and has higher timeliness. The research in this paper helps to explore the possible path to ensure the resilience and safety of the industrial chain, and then provides beneficial theoretical support for achieving high-quality development under the new round of scientific and technological revolution.

Since the 18th National Congress of the CPC, president Xi Jinping has attached great importance to the work of propaganda, ideological and cultural work. He has profoundly summarized the achievements and experience of building a culturally strong nation in the new era, and has deeply contemplated the opportunities and challenges faced by cultural development in the new circumstances. He has put forward numerous new thoughts, new viewpoints, and new judgments in the construction of cultural development, which have formed Xi Jinping's Thought on Culture. Existing literature primarily focuses on exploring the historical process, main content, and original contributions of Xi Jinping's Thought on Culture. However, the research is still in its early stages, and there is room for improvement in terms of theoretical depth and breadth. This paper primarily adopts the methods of literature research and systematic analysis, aiming to comprehensively sort out and systematically analyze a series of important discourses by Xi Jinping on Cultural development. The goal is to conduct an in-depth and specific investigation into the logical generation, core essence, basic characteristics, and contemporary value of Xi Jinping's Thought on Culture. Through these efforts, the aim is to deepen the theoretical interpretation and holistic research of it. Compared to previous literature, this paper innovates in three aspects. Firstly, it analyzes the logical generation of Xi Jinping's Thought on Culture from four perspectives. It argues that these thoughts are based on the theoretical foundation of cultural development by Marxist classic writers, the historical experience of positive achievements in cultural development by the Communist Party of China over the past century, the practical experience of party leadership in cultural development in the new era, and the rich cultural heritage of the Chinese nation. These four aspects together establish a solid foundation for Xi Jinping's Thought on Culture. Secondly, it specifically examines the core essence of Xi Jinping's Thought on Culture. Xi Jinping's Thought on Culture is rich in content and profound in connotation, systematically elucidating a series of contents such as the strategic position of cultural construction in the new era, the new cultural mission, the work orientation and fundamental principles of propaganda, ideological and cultural construction, the road to cultural prosperity, and the important impetus for cultural development, formed a complete scientific system. Thirdly, it summarizes six distinct characteristics of Xi Jinping's cultural thoughts: the unity of party nature and people-oriented approach, the unity of adherence to principles and innovation, the unity of holistic thinking and practicality, the unity of historical confidence and cultural confidence, the unity of national character and global perspective, and the unity of systematic thinking and openness. It argues that the introduction of Xi Jinping's Thought on Culture greatly enriches and develops Marxist cultural theory, provides scientific guidance for the construction of a strong cultural country in the new era, and contributes Chinese wisdom to the development and progress of human civilization. The research conducted in this paper, to a certain extent, enriches the theoretical exploration of Xi Jinping's Thought on Culture. It is beneficial for further clarifying the scientific connotation, practical requirements, and significant implications of Xi Jinping's Thought on Culture. Moreover, it is advantageous for promoting the in-depth and solid implementation of learning and applying Xi Jinping's Thought on Culture throughout the entire Party and society.

The achievements of ecological civilization construction in the new era have attracted worldwide attention and become a significant symbol of historic achievements and transformation in the cause of the Communist Party of China (CPC) and the Chinese nation in this era. Based on the perspective of ecological and environmental governance modernization, this paper summarizes and reviews China's green development in the decade of the new era. From the perspectives of green development system and mechanism, ecological environment quality, green economic transformation, green and low-carbon life, and global sustainable development, this paper statistically demonstrates the results of China's green development in the new era in the past decade. Guided by the five major relationships of coordinated promotion of carbon reduction, pollution reduction, green expansion, and economic growth, the study proposed an optimized path to further promote green development on the new journey towards modernization. Green development is a new development model formed by the CPC after unremitting exploration and a profound revolution in the development concept. It includes aspects of the green transformation of the economy and the development of a green economy and has profound theoretical logic, historical logic, and realistic logic. In the decade from the 18th to the 20th CPC National Congress, China took multiple measures to improve its governance system, promote environmental co-governance through multi-dimensional interaction, implement governance measures scientifically and effectively, and improve governance effectiveness in a multi-pronged approach, successfully exploring a green development path that conforms to nature and promotes harmony between humanity and nature. In that decade, China had continuously improved its institutional mechanisms for green development, achieved overall improvement in ecological and environmental quality, made important progress in green economic transformation, and made green and low-carbon living a new trend, contributing China's strength to global sustainable development. China has created a world-renowned ecological miracle and a green development miracle, and green development has become a prominent feature in pursuing a Chinese path to modernization. We should fully understand the new tasks and requirements put forward by the 20th CPC National Congress, analyze the new situation and problems currently faced, and continue to promote green development on the new journey. We must effectively strengthen the concept of the system, jointly promote carbon reduction, pollution reduction, green expansion, and economic growth, and accelerate the formation of a mechanism to coordinate the relations between these four aspects and correctly handle the five major relationships. And we will accelerate the modernization of harmony between humanity and nature, cultivate a green feature for high-quality development, and promote the steady and long-term development of green development in China.

Protein-protein interaction (PPI) participates in almost all important biological processes in the organism and plays a vital role in the basic life process of cells. It is of great biological significance to develop a high-throughput PPI detection method. At present, the next-generation sequencing (NGS) technology has developed rapidly and can determine more than 1 billion template DNA sequences in a few days. Due to the unique sensitivity, specificity, high throughput, and multiplexing advantages of parallel DNA sequencing technology, it has been used as a broad-spectrum molecular counter and applied to genome sequencing, transcriptome sequencing and other fields. The nucleic acid barcode technology realizes the high-throughput detection of PPI by connecting the oligonucleotide tag with the target proteins to mark the encoded protein, and then using the high-throughput sequencing method to detect the interacting protein. This technology promotes the rapid development of PPI detection methods, improves the throughput of single experiment detection, and provides a strong technical support for building PPI network. In this paper, we describe in detail the design, generation and reading of nucleic acid barcodes in the PPI detection method. By analyzing the application examples of the nucleic acid barcode technology in PPI research, this paper discusses their advantages and disadvantages, evaluates the reliability of data, and discusses the future development trend of PPI detection methods based on the nucleic acid barcode technology.

Aiming at the problem of small scale and difficulty in taking into account multiple indexes in the design of frequency-hopping sequences, this paper proposed a frequency-hopping sequence design method based on large-scale multi-objective optimization. Firstly, considering the multiple performance indexes of frequency-hopping sequence,this paper established a multi-objective optimization model of frequency-hopping sequence. Then, this paper introduced a large-scale multi-objective optimization algorithm, and proposed the decision variable shuffling strategy and the opposition-based differential evolution, which could form a diverse non-dominated set by redistributing the position of decision variables and provide an effective direction for subsequent evolution by enabling reverse individuals to participate in differential evolution and provides an effective direction for subsequent evolution. Finally, this method used the proposed algorithm to optimize the model to obtain a frequency-hopping sequence set. The experimental results show that the proposed algorithm has stronger optimization ability than other multi-objective optimization algorithms,and the performance indexes of the frequency-hopping sequence set has obvious advantages. In different interference environments, the proposed design method has lower bit error rate than other methods, which verifies the effectiveness and superiority of the proposed method.

Federated learning enables different clients to collaborate and train a shared model while preserving user privacy. Motivating high-quality clients to participate in federated learning is crucial. In online federated learning environments, where clients join and leave training dynamically, evaluating and selecting clients in real-time poses a challenge. To address this challenge, this paper proposed an online federated learning incentive algorithm to optimize client selection and budget allocation, thereby enhancing the performance of federated learning under budget constraints.The proposed algorithm divided the budget into stages and computed optimal quality density thresholds based on historical sample information. The main idea was to dynamically assess the quality of client models and employ a quality threshold admission mechanism while limiting the number of participating clients. In theory, this paper proved that the incentive algorithm satisfied incentive compatibility, budget feasibility, and individual rationality. Experimental results demonstrate that the proposed online incentive algorithm achieves good performance in scenarios with different proportions of free-riding clients. Specifically, compared to existing methods, it achieves approximately 4% and 10%improvements on the EMNIST-B and CIFAR-10 datasets, respectively, under sufficient budget and in the presence of free-riding and mislabeled clients.

In order to solve the problem of limited channel resources of the Internet of Things (IoT) and improve the information timeliness of the IoT system, this paper considered a multi-access Cognitive Radio (CR) IoT system model including one Primary User (PU) and two Secondary User (SU) nodes. Under the constraint of PU working state and SU data queue stability, the paper analyzed the average Age of Information (AoI) of the First Secondary User node in the First Come First Served (FCFS), Last Come Last Served (LCLS) and the packet dropping queue, and derived the average AoI of the second SU node in the threshold strategy. Then, the paper proposed an optimization problem to minimize the average AoI of the first user and lower the average AoI of the second user below the given threshold. The constraint condition of the problem was convex, but the objective function was non-convex, so the paper introduced a suboptimal technique and obtained the optimal solution by double convex optimization algorithm. Simulation results show the performance of the proposed algorithm under different system parameters, and the algorithm performs well under the influence of different system parameters and multiple antennas. Subsequent work can consider extending CR IoT system to more than two SUs. [ABSTRACT FROM AUTHOR]

To study the evolution process and community structure of e-commerce networks, this paper uses AN improved stochastic block model (sbm) link prediction algorithm. since the degree distribution among blocks in the original sbm model is binomial, to make the degree distribution among blocks follow the power law distribution in the stochastic block model, this paper introduces the degree attenuation parameter. aiming AT the assumption that the connection between nodes depends only on the block to which nodes belong in the original sbm model, to make the degree distribution closer to the real network, the paper introduces the degree control parameter. based on this, the paper proposes AN optimized random block model, and use the alibaba taobao data set to verify the proposed algorithm. the results show that the accuracy of the proposed algorithm is higher than the sbm, the degree-corrected stochastic block model (dcsbm) and the hierarchical structure model (hbm). it shows that the improved algorithm can describe the community structure of the e-commerce network well and find the missing link in the network accurately.

Most existing deviation detection methods are capable of identifying deviations from process activities and data attributes, but they fail to address the issue of how changes in data during process execution impact the process,especially in cases involving interactions among multiple objects. To address this issue, this paper proposed a business process deviation detection method based on data impact in the context of multi-object interactions. Firstly, this method identified potential deviant activities based on control flow and data information. Then, it defined impact sets based on the impact of data changes on activities. Next, it introduced the concept of object-centric into the deviation detection process and formalized the object-centric Petri net model. On this basis, by analyzing whether the object has execution privilege on the data it modified, this paper classified and defined four types of data impacts and their calculation criteria,from which the results of deviation detection based on data impacts were obtained. Finally, compared with other deviation detection methods, the results show that the deviation detection results obtained by applying the method are improved and are able to handle process deviations for multi-object interactions. This method can effectively capture the process activities affected by data changes in multi-object interaction processes and improve the rationality and accuracy of deviation detection.

The storage of massive point cloud data has great significance to the real-time 3D collaborative perception of autonomous driving. However, due to the requirements of data security and confidentiality, some data owners are unwilling to share their private point cloud data, which limits the improvement of model training accuracy. Federated learning is a computing paradigm that focuses on data privacy and security. This paper proposed a novel approach based on federated learning to address the challenge of large-scale point cloud semantic segmentation in collaborative vehicle perception scenarios. It integrated position encoding with inter-point angle information and geometric diffraction of neighboring points to enhance the feature extraction capability of the model. Finally, it dynamically adjusted the aggregation weights of the global model according to the generation quality of the local model to improve the ability to maintain the local geometric structure of the data. This paper applied the proposed method on three datasets, such as Semantic KITTI, SemanticPOSS and Toronto3D. The results show that the proposed approach significantly outperforms the single training data and the FedAvg-based method, and fully exploits the value of the point cloud data while taking into account the privacy sensitivity of each party's data.
